Alamo Heights sits inside our San Antonio service area, but its housing stock tells a different story than the suburbs surrounding it. The homes here weren’t built around central air. They were adapted to it, often clumsily, and that adaptation is where the problems start. We’ve spent over a decade tracing those problems to their source.

Why Alamo Heights Homeowners Choose Bellows Air Duct & Vent Co. of Texas

They inspect with cameras before touching a tool, and they show the homeowner exactly what they found.

Why Alamo Heights’s Climate & Housing Affect Air Duct Cleaning
Alamo Heights is a small, completely built-out enclave of affluent mid-century homes, many dating to the 1940s-1960s, that were originally built without central air conditioning and later retrofitted with ductwork threaded through existing wall cavities and attic spaces. Because these retrofit systems were never designed around the home’s structure, they have poor sealing, frequent disconnects at joints, and long attic runs. All of this compounds in San Antonio’s brutal heat and the region’s notorious Ashe juniper (mountain cedar) allergy season, creating a local air-quality problem that newer-construction suburbs simply don’t share.
Summers here push attic temperatures above 150°F. That heat accelerates flex-duct liner degradation and causes repeated thermal expansion that loosens duct joints in older systems. Meanwhile, the Hill Country’s Ashe juniper pollinates aggressively every December through January, one of the most intense allergen events in the United States. The fine pollen infiltrates through leaky ducts and accumulates in layers inside aging duct systems year after year. Our technicians working the ’09 regularly find a characteristic tan, fibrous cedar-pollen buildup layered inside original 1950s-60s galvanized duct runs, sometimes multiple distinct seasonal strata, because the homes’ leaky, unsealed duct joints pull unconditioned attic air heavily loaded with Hill Country pollen directly into the supply stream during the HVAC’s negative-pressure draw.
The housing stock itself compounds the issue. Pre-1970s Tudor revival, Colonial revival, and ranch-style homes in Alamo Heights carry ductwork that was retrofitted rather than purpose-built, leaving behind mismatched materials, undersized chases, and minimal joint sealing. Homes that have cycled through multiple HVAC equipment upgrades over the decades frequently have orphaned duct branches or mixed flex-and-metal systems stapled into unconditioned attic spaces. Cleaning these systems requires more than equipment. It requires understanding what was cobbled together and why.

FAQs About Air Duct Cleaning in Alamo Heights
Most full residential cleanings in Alamo Heights run $350-$650 depending on system size and condition. Homes with original 1950s-60s retrofit ductwork or heavy cedar-pollen accumulation may fall toward the higher end. Call (866) 347-2063 for a free estimate with upfront pricing.
Every three to five years for typical households, though Alamo Heights’s combination of aging retrofit ductwork and intense Ashe juniper pollen season often warrants more frequent inspection. If you notice increased dust, worsening allergies, or uneven airflow between rooms, schedule a camera inspection. We’ll show you what’s inside without pressure to book cleaning.
Yes, and this is where experience with local housing stock matters. Our technicians are trained to work with the mixed flex-and-metal systems, undersized chases, and fragile joints common to pre-1970s Alamo Heights homes. We adjust equipment pressure and brush selection based on what the camera reveals, and we document condition before beginning work.
Repair and sealing is usually more cost-effective than full replacement in Alamo Heights’s retrofit systems, provided the underlying materials are structurally sound. Replacement becomes necessary when galvanized runs are corroded through or flex liner has degraded from years of 150°F attic exposure. Our camera inspection determines which path makes sense for your specific system, and we’ll explain both options with pricing before you decide.
We answer calls live 24 hours a day and schedule most Alamo Heights appointments within 24-48 hours. True emergencies, such as a disconnected main trunk line or complete airflow failure during summer heat, receive priority dispatch. Call (866) 347-2063 and a live person will coordinate timing.
